Internal: Problems with Ctrl-C and Ctrl-V copy and paste on Linux

A customer reported that when he tries to copy and paste from an Editor window in the IDL 7.0.6 workbench on Fedora Core 7 using Ctrl-C and Ctrl-V, the paste operation usually pastes the content from the Ctrl-C before the most recent one. He has to then Ctrl-C and Ctrl-V the same item a second time to get the copy and paste to work.Discussion:
We tested this on a Fedora 10 machine running IDL 7.0.6, and could not reproduce. The customer did some testing, and discovered the following:

After downloading and installing a clean version of IDL 7.0.6, copy and paste worked properly again. This installation did not have several Eclipse plug-ins that his previous installation had: a C/C++ plugin, a Perl plugin, and a Subversion plugin. So, he concluded that the non-ITT plugins (presumably one of the editors specific to those plugins) was messing up the Editor behavior in IDL.

He was also using KDE, and later I found that configuring Klipper (KDE's copy buffer) to uncheck "Prevent empty clipboard" improved the reliability of copy/paste. He found a posting on the internet talking about doing the opposite, regarding Eclipse and KDE. He tried all the combinations and found that checking "Prevent empty clipboard" causes copy/paste to become unreliable in IDL.
